I used to have a friend (we where 11 and 12 when we met)
We had dc at around the same time and they grew up together
Mine where not angels (and I'm hardly a perfect parent) but good god,hers was a terror
1st dc,1st grandchild,1st great grandchild,1st nephew etc and whatever he wanted,he got (i was a skint single parent and simply couldn't afford what he was getting) and he could do no wrong
He was a low key bully and a snob at school (I kept him in check around my lot) and she was tearing her hair out at his behaviour (she would tell mine off,which was fine but refused to do the same to him and god help you if you tried)
She tried to have him diagnosed with adhd but he didn't have it-the professionals told her she needed firmer boundaries (she refused to listen as she was the perfect parent) and he carried on being a little sod
When he was 7,she had his baby sister and 2 years later,another baby girl
He really ramped up his behaviour,thinking nothing of biting/punching/hitting the babies/her and started spitting and making an annoying sound (it's hard to describe but it was irritating)
Again,nothing to do with her parenting and he was perfect (she even tried to blame it in the babies crying and him being jealous)
When he turned 11,we where invited to his birthday party
We walked the 3 miles from our house to hers and knocked on the door
He leant out of the window above the front door,making that annoying sound and he spat at me
I'm standing there,covered in spit,my dc looking agog at me and she opened the door to find a pissed off me and him laughing at the top of the stairs just behind her
I told her what he'd done,and she turned around and asked if he'd done it
He said 'no' (still laughing) and she turned back and told me he couldn't have done it as he'd not been upstairs all morning (he's still hanging out of the upstairs window!)
I just looked at her,shook my head,told her to pull her head out of her arse and walked away
I never spoke to her again-a friendship of over 25 years over because she couldn't see what was right in front of her
Fast forward and mine either have a good career/are studying and he spends all her money on weed and junk food and cant hold down a job longer than a fortnight
I have no regrets but am sad at losing the friendship
